PATENT FFICE WINDOW-FASTEN ER.

SPEGIFICA'I'IONforming part of Letters Patent No. 742,882, dated November 3, 1903.

Application filed June 25 I 1903.

To all whom it may concern.-

Be it known that I, ORTON C. LITTLE, a citizen of the United States, residing at Menasha, in the county of Winnebago and State of Wisconsin, have invented an Improvement in Window-Fasteners, of which the following is a specification.

My invention relates to a window-fastener which is applicable to either the upper or lower sash of sliding windows and when properly applied to the upper sash, it raised to its highest limit, will securely lock it in that position, and when applied to a closed lower sash will lock the same and will also hold either sash at any desired point in its movement; and it consists of a single short bolt to be inserted into a circular aperture bored from the outside edge in one of the window-sash stiles and having a perforation through the inner end of the bolt and a long vflat and smooth head, the face of which latter is at right angles with the bolt for engaging with the jamb of the window, a spring being arranged around the bolt for holding the bolthead pressed outward againsfi the windowjamb, a lever being pivotally secured to the inside of the sash-stile, the lever having an arm eccentrically located with reference to said pivotal point and engaging with the aforesaid perforation, whereby the lifting of the free end of said lever will compress said spring and draw the bolt-head away from the window-jamb, the device being illustrated in the accompanying drawings, in which Figure 1 is a sectional view across the stile of a window-sash, showing the fastening-bolt inserted therein and its operating-lever applied to the sash and engaged with the bolt. Fig. 2 is an elevation showing the bolt and its operating-lever detachedfrom the sash and as it appears in looking from the left-hand side of Fig. 1 or the back side of the bolt and lever. Fig. 3 is a plan of the bolt upon the inside of the head. Fig. 4: shows a vertical section of the upper and lower sash of a window with the usual parting-strip between the sash, parts being broken away in their length for want of room for showing the entire window, and the bolt-releasing lever applied to each sash. Fig. 5 shows a section of the top and bottom rail of the lower sash and the sash-stile at the right-hand side of the sash Serial No. 162,989. (No model.)

with a section 'of the window-jamb, parts of the sash and jamb being broken away and a part of the jamb being in section, with my improved fastening device applied to the stile and the bolt-head engaged with the window-jamb for securely locking the sash.

Figs. 1, 2, and 3 are upon the same scale, and

Figs. 4 and 5 upon the same, but a reduced, scale.

Similar numerals indicate like parts in the several views.

1 indicates a part of a window-jamb having a shallow mortise 2 therein; 3 and 3, the window-sash top rails; at and 4:, their bottom rails; 5, their stiles, and 6 the glass of the window.

7 indicates the window-fastening bolt having an aperture 8 and head 9, the head having wings 9.

10 is a spiral spring upon the bolt. The

bolt is to be inserted into the stile of the sash by boring a hole 11 of a diameter for easily receiving the spring 10 and of a depth suflicient for the length of the spring and so that the inner end of the spring will rest upon the bottom of said bore and throw the bolt-head outward by the compression of said spring between said bottom and the bolt-head. Below the bottom of the bore 11 a smaller bore 12 is made of a suitable diameter and depth for receiving the bolt and allowing the bolt-head and wings to be mortised into the stile, so that the head will be flush with the outside of said stile. The purpose of the wings 9 is to retain the bolt-head in position and guide its reciprocating movement. There may be one or more of said wings and of any suitable form.

13 indicates the operating-lever, 14 the pivotal screw-hole therein, and 15 is an arm which projects at right angles from its inside face directly under the screw-hole for engaging the aperture 8 of the bolt. The body of the operating-lever consists of a fiat plate of metal flat upon its inner side and is provided with a handle 16, which is so shaped that when it is applied to a sash-stile it does not project from the face of the stile but little if any more than the thickness of the body of said plate; but its outer or free end is curved downward and widened out for providing a suitable finger-hold for the operator to grasp .between the thumb and finger for lifting said end and withdrawing the head of the bolt away from the window-jamb. The spring is arranged around the bolt between its head and the arm 15 and should be of such a degree of resiliency as to hold the sash at any point of its sliding movement that may be desired by reason of the frictional contact with the window-jamb of the bolt-head. Opposite the bolt-head of the lower sash when the sash is down a mortise 2 is to be made in the window-jamb for receiving the head 9 of the bolt, which mortise may be from one-sixteenth to one-eighth of an inch deep. Upon closing the window the bolt-head will enter this mortise and securely lock the window. When the upper sash is raised to its highest limit, a mortise is to be made opposite the bolt-head and similar to the mortise in the jamb for the lower sash for the entrance therein of the bolt-head. The sash is therebylocked against being lowered until the bolt is retracted by means of its operating-lever. This mortise should be extended about onefourth of an inch higher than the upper end of the bolt-head or its upper shoulder cut away, so that if said sash should be loose between the jambs and the sash inclined to sag away from its highest position upon lifting both sides of the sash the bolt-head will have sufficient space for allowing of said lifting and will hold the sash at said highest limit by reason of the force of the spring against the bolt-head and the engagement of said head with the jamb, while the entrance of the head into the mortise will prevent the sash from being lowered from the outside.

The head of the bolt has a flat smooth face of more length than breadth for frictional engagement with the window-jamb, each end of said head being slightly rounded, as is shown at 9', for its smooth movement along the jarnb without any liability of its corners cutting into the wood of the jamb.

In applying the operating-lever a slot 17 is to be made in the sash-stile opposite the aperture 8 of the bolt for' the entrance of the arm 15 into the latter aperture and of sufficient length for the necessary reciprocation of the bolt. The lever is then to be placed in position and a wood-screw 18 inserted through the perforation 14 into the sash. No other fastening is required, as the bolt is seated in the bore 12 and in the mortisesfor the wings 9. A corner 3" will require to be cut from the top rail 3 of the lower sash for allowing the raising of the lower sash without the interference of said rail with the lever and its securing-screw 18.

The operation of the device is as follows: For opening the lower sash the operator with one hand lifts upon the sash by means of the window-lift upon the bottom rail or otherwise and at the same time with one finger lifts upon the free end of the lever. Then in lowering the sash only a pull downward upon the top rail is necessary, or if the resiliency of the spring is too great for its easy lowering a slight lift upon the operatinglever handle will relieve the tension of the spring and permit the easy lowering of the sash, the sash sliding easily and smoothly up or down until the bolt-head enters a mortise in the jamb. For lowering the upper sash the bolt-head must first be disengaged from the mortise in the jamb, when a pull downward upon the sash is all that is required.

It should be observed that the force used in retracting the bolt assists also in raising the sash, and as both sash in a closed window require to be raised, the upper one for the easy release of the bolt-head 9 from the bolthead mortise in the jamb, this is an important feature in its easy and successful operation.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s 4 "In a window -fastener having a springpressed bolt adapted to be inserted in the outside edge of awindow-stile for its engagement with the jamb of the window and being provided with an aperture through its inner end, the combination therewith of an operatinglever consisting of a plate, flat upon its inside face and said face being provided with an aperture for receiving a screw upon which said lever can be pivotally secured to the sash-stile, an operating-handle extending outward from one edge of said plate, an arm extending inwardly from said plate at right angles therewith, and being adapted to engage the aperture in said bolt, whereby the force employed in the upward movement of the handle or free end of said lever will retract said bolt and simultaneously also, assist in raising the sash to which scribed.
